It exists, but "works quite well" is only for a small amount of heat. It takes a big radiator to get rid of heat to ax vacuum. Much easier and cheaper to just keep the computers on earth and cool them with standard air or liquid cooling setups.

The required radiator for cooling isn’t that much larger than the required solar panel for powering the thing in the first place, and you don’t see everyone saying those are impossible. Is it easier to keep them on the ground? Obviously, but that wasn’t the claim. It just isn’t nearly as hard to cool things in space as a lot of people seem to think.
